Some 100 percent of sales of Joan Hornig’s Wave of Hope necklace in sterling silver will benefit Japanese relief efforts. The retail price of the piece ($60.80) reflects the geography of the Sendai Earthquake-Tsunami: 80 miles from the eastern coast of Japan, traveling 6 miles inland.

Bidz.com has added a Tsunami Relief section to its site, where 100 percent of proceeds from specific sale items will benefit the victims of the Japan earthquake and Tsunami.
